CASTING FOR FEEDER-S FOR INGOT MOLDS. l

Application filed February 15, 1924. Serial No. 693,092.

To all whom t mar/concern.'

Be it known that BLooMriELD H.- HOWARD and ERNEST J. TURNER, citizens of the United States, residing, respectively, at Vashington, District of Columbia, and Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Castings for Feeders for Ingot Molds, of which the following is a specification.

Our invention relates to improvements in castings fory feeders for ingot molds.

The object of our invention is to provide a casting for forming ingot molds of plastic material by forcing the material under pressure through a passage to form a feeder having' a Ylarge number o-f walls and ribs on the outer face to correspond with that shown in s an application of even date.

` Another object of our invention is to provide a castingin which the outer walls of the passage are straight and connected by curved walls forming supporting ribs and said ribs connected by curved walls whereby a feeder is formed by a single operation.

A further object of our invention is to provide a specially shaped casting adapted to form a correspondingly shaped feeder and having certain arrangement of parts hereinafter more fully described.

In the accompanying drawings Figure 1 is a vertical sectional view of the lower end of a cylinder having our improved casting attached thereto.

Figure 2 is a horizontal sectional view of Figure 1.

Figure 3 is a horizontal sectional view similar to Figure 2 showing an oblong'casting.

Figure 4 is a horizontal sectional view similar to Figure 3 Showing the inner member having straight walls with rounded corners.

Referring now to the drawings 1 represents the lower end of the cylinder which is provided `with an outwardly extending flange 2 to which is clamped the flange 3 of the outer member 4 of the casting by means of bolt 5. In this form the outer member 4 is provided with four oppositely arranged straight walls 6, 7, 8 and 9 the ends of which having connected thereto the outwardly curved walls 10 and 11 connected by an intermediate curved wall 12. The walls 10 and 11 form the supporting ribs on the outer face of the feeder.

The cylinder 1 is provided with a cylindrical .member 13 to which is bolted the casting by means of member 14 of the casting is provided with four straight walls 16,

inner member of the bolts 15.. The inner 17, 18 and 19 beveled as indicated at 20. The walls of the outer member are also beveled as indicated at 21 and whereby of the/plastic material whereby it is compr through the casting.

In the modifications shown an oblong casting the upper end of the passage is flared outwardly to allow the ready entrance into the passage and essed in its passage in Figure 3 we have constructed exactly In Figure 4 we have shown the outer member 'the Same as shown in Figure 2 and like numerals indicate like member 14 has rounde parts, while the inner d corners 22.

Having thus fully described our invention what we claim is :f

1. A casting for fee comprising an outer ders for ingot molds, member having four oppositely arranged straight walls connected by curved walls.

2. A casting for feeders for ingot molds,

comprising an outer oppositely arranged straight walls connected by curved walls, an

member having four d an inner member.

3. A casting for ingot mold feeders comprising an outer member having four oppositely arranged straight walls connected at the corners by curved walls and an inner member having four straight walls.

4. A casting for ingot mold feeders comprising an outer member having four OPPO- site straight-walls connected by three outwardly curve-d walls and an inner member oppositely arranged parallel having four straight walls.

5. A casting for feeders for ingot molds comprising an outer oppositely arranged straight walls connected to the ends of each wall member having four and outwardly curved walls connected by an outwardly curved wall arranged in a different arc of a circle and an inner member having four straight walls oppositely arranged and paralled with the straight walls of the outer member.

6. A casting for feeders for ingot lmolds comprising an outer oppositely arranged St comprising oppostely arranged straight Walls and out- Wardly Wardly curved walls arranged at the end of keach of `the Straight Walls and lia-ving an inner member with straight side Walls rounded at the corners.

In testimony whereof we afx our signai5 tures.
